A congestion-resilient link adaptation method is provided. The link adaptation method for selecting any one of modes having mapped transmission parameters includes the steps of: estimating a channel-induced error number indicating the number of channel-induced transmission failures in a current mode and comparing the estimated channel-induced error number with a mode-down threshold; and determining whether the mode-down is performed based on the comparison result. Thus, higher throughput can be achieved without use of additional hardware or protocols.
